Health officials said there are no new cases, but they also have no new answers.

Some people are still questioning the way the public was notified of the outbreak.

Cumberland School is one of the few places where the North Shore Health Department notified families of the crypto outbreak, but the warning never went out to other schools, including Holy Family, which is right across the street.

That has some wondering why, and others throughout the community taking it upon themselves to spread the word.

The Whitefish Bay High School pool is open again. It's one of the spots being investigated as the possible source of the outbreak, which has sickened up to 20 people.

"What was your first reaction when you heard about it?" WISN 12 News reporter Kent Wainscott asked a parent.
